DFRobot Gravity Digital HX711 Load Cell 1Kg Weight Sensor Kit

The Arduino electronic weight sensor can detect a weight of 1 kg and is based on the HX711, a 24-bit analogue-to-digital converter for scales and industrial control applications. It uses the DFRobot Gravity Interface for easy connection, making it a good choice for electronics enthusiasts who want to build small scales for the home.

Features:

• Active low noise on-chip PGA with selectable gain of 32, 64, and 128.
• On-chip power supply regulator for analogue load cell and ADC supply.
• On-chip oscillator requiring no external components, with optional external crystal.
• On-chip power-on-reset.
• Simple digital control and serial interface: pin-driven control, no programming required.
• 16-pin SOP-16 package.
